Abstract
We study the behaviour of the poles of a scattering matrix for the situation where the internal Hamiltonian corresponds to an’ ordered’ system, i. e. has Poissonian spectral fluctuations. In the region of strong coupling between bound and scattering states where most of the resonances have small widths again, we find that the poles show GOE-like level statistics, typical of chaotic systems.
